WaterSlim: the first flat water heater in the world

For more than 50 years the cylindrical shape of large water heaters didn’t change.

The idea was simple, almost obvious: forget the traditional shapes to save space and obtain a flat water heater that can fit in kitchens and bathrooms.
To take an ingenious idea and make it an effective device, the teams from WaterSlim faced a dual challenge. Challenges of design and technology.

Behind its revolutionary shape are months of studies, development, testing and certification. The skills required were provided by professionals from a variety of fields, and in particular from Formula 1 racing.

The flat water heaters (100L and 50L) offer space savings, great design, energy efficiency, and strength (100% stainless steel tank)
